The New York Times covers the darker side of rare earth element mining in China. Rare earth’s are vital to many “green” technologies but they still need to be mined from somewhere. Right now, somewhere=China.
There are 17 rare-earth elements — some of which, despite the name, are not particularly rare — but two heavy rare earths, dysprosium and terbium, are in especially short supply, mainly because they have emerged as the miracle ingredients of green energy products. Tiny quantities of dysprosium can make magnets in electric motors lighter by 90 percent, while terbium can help cut the electricity usage of lights by 80 percent. Dysprosium prices have climbed nearly sevenfold since 2003, to $53 a pound. Terbium prices quadrupled from 2003 to 2008, peaking at $407 a pound, before slumping in the global economic crisis to $205 a pound.
China mines more than 99 percent of the world’s dysprosium and terbium. Most of China’s production comes from about 200 mines here in northern Guangdong and in neighboring Jiangxi Province.
